Insider Risk Management Data Protection

    Your security stack already knows who’s at risk — it just can’t tell you

    The data that identifies your highest-risk employees sits siloed across tools that were never built to talk to each other — here’s how to unify it into a single, actionable view

    Key Points

    • Organizations need to be able to identify which employees are the most at risk — based on their actions, the attacks targeting them, and their access to sensitive data. In the age of AI, that picture changes faster than ever.
    • Your security stack already has the data you need to identify and control who is most at risk; you just need the right solution to surface it and put it to work.
    • Mimecast’s Human Risk Command Center allows you to not only identify which team members are likely to be the riskiest operators, but also who is being targeted specifically by threat actors, making it a launchpad for human risk intervention and response.

    A large company makes the news. A breach, started with a phishing email, spread through a compromised account, data exfiltrated before anyone connected the dots. Your CEO forwards the article to your CISO with a single question: Are we prepared for something like this?

    Your CISO turns to the security team. The security team opens tabs — the endpoint platform, the email gateway, the identity provider. Each one has something. Detections. Click data. Anomalous logins flagged last month. All of it’s real, but none of it’s connected to a name, or to each other, or to any coherent picture of who in the organization is actually at risk right now.

    That’s the honest answer to the CEO’s question: We don’t know yet. Give us ’til Wednesday.

    The numbers are consistent across every major breach report: most incidents involve people. The problem isn’t detection. The problem is correlation. None of those tools were built to tell you which specific employees are your highest risk, right now, across every dimension simultaneously.

    Why the signals don’t add up

    Endpoint detections sit in the EDR console. Identity risk events sit in the IAM platform. Sensitive data violations sit in the data security tool. Ask any security analyst for a cross-stack risk view, and the honest answer is: It takes a spreadsheet and an afternoon.

    According to Mimecast platform data, the 8% of employees who account for 80% of security incidents stay hidden in plain sight — not because their behavior is invisible, but because the signals are scattered across tools that were never designed to talk to each other. According to Mimecast’s State of Human Risk Report 2026, only 28% of organizations currently combine security awareness with continuous risk monitoring — most are making decisions about human risk with half their instruments.

    AI didn’t create this problem. It multiplied it. As AI-powered attacks grow more sophisticated and autonomous agents introduce entirely new data exposure pathways, the gap between organizations that can answer the readiness question and those that can’t is widening faster than ever. Correlation can’t wait.

    This is the gap the Human Risk Command Center was built to close.

    What makes Mimecast’s human risk intelligence different

    Before discussing what the Command Center surfaces, it’s worth understanding what powers it. Mimecast has spent more than 20 years protecting enterprise email, inspecting 1.8 billion emails every day across 42,000 customers worldwide. That scale produces something no point solution standing up a human risk dashboard in 2026 can replicate: a continuously learning social graph that maps communication relationships and behavioral patterns across the world’s largest network of protected organizations. Every email signal, every anomaly, every sender-recipient relationship feeds a model that gets more accurate over time — and that intelligence is part of what powers our human risk scoring at the individual level.

    What unified human risk intelligence actually looks like

    The Command Center aggregates behavioral signals from across your security stack — email, endpoint, identity, and data security — and normalizes them around the individual.

    The result is a Human Risk Score for every employee: a live, weighted composite built from six behavioral categories — identity, malware, sensitive data handling, email, phishing, and training. Scores update continuously as new events arrive and decay automatically as behavior improves. The Command Center also calculates a separate Attack Factor per user, measuring how frequently and severely someone is being targeted by external threat actors — independent of their own behavior. That distinction matters, and it shapes the response.

    The Command Center connects 19 first- and third-party integrations across all six scoring categories — including CrowdStrike, SentinelOne, Okta, Microsoft Entra ID, CyberArk, Netskope, and others, alongside four native Mimecast integrations spanning email security, phishing simulation, training, and sensitive data handling. For organizations already running these tools, the Command Center puts that intelligence to work across your existing security stack without signing a new contract or building new data pipelines. It’s available to Mimecast customers at no additional cost, and most integrations go live in minutes.

    “It’s quite possible for us to have an email flagged in Mimecast and then execute tasks outside the Mimecast environment. We could block a website with Netskope because a user clicked a link in an email. We could isolate a machine with CrowdStrike because of an email triggered in Mimecast. Platforms can no longer exist on their own. No one vendor can do it. It’s a team sport.”

    From insight to action

    The difference between knowing who’s risky and doing something about it is where most programs stall. The Command Center is designed to close that gap — automatically, in real time, without requiring a human to manually connect the dots.

    Here’s what that looks like in practice.

    The repeat clicker who just had a real phishing incident. An employee has a history of clicking simulated phishing links. Last week, they clicked a real one — flagged by Mimecast email security. Their Human Risk Score crosses a threshold. The Command Center automatically adds them to a watchlist, tightens their email security policies in real time, and triggers a targeted 30-second behavioral nudge through Mimecast Engage — delivered directly to their inbox within hours of the incident, not at next month’s training session.

    The highly targeted executive with clean behavior scores. A senior leader has a low Human Risk Score — never clicked a simulated link, training is current, no sensitive data violations. But their Attack Factor is elevated: they’re receiving a high volume of sophisticated, targeted phishing attempts. The right response isn’t more training. It’s stronger defenses. The Command Center surfaces this distinction explicitly, so security teams apply the right intervention — tightened policy, additional controls, closer monitoring — without misreading a targeting problem as a behavior problem.

    The AI agent nobody approved. A member of the finance team uses MCP to connect an unauthorized AI tool to the company’s CRM. The action triggers a sensitive data event, which feeds into the Command Center alongside an elevated identity risk signal from Okta flagging unusual access patterns. The Command Center correlates both signals against the user’s existing risk profile and automatically escalates their score and tightens controls. As AI agents proliferate across the enterprise, the human behind the agent remains the signal that changes everything. Mimecast’s Agent Risk Center extends this visibility to autonomous agents themselves, connecting human and agent risk into a single, actionable picture.

    For teams looking to extend human risk data further, the Human Risk Public API pushes scores and behavioral events directly into SIEM, SOAR, and identity platforms — human risk as an active input to automated playbooks and custom dashboards, not just something the awareness team checks on Fridays.

    Back to Wednesday

    The CEO’s question was about readiness. The honest answer — at most organizations — is that the data needed to answer it already exists. It’s in the endpoint platform. The email gateway. The identity provider. The data security tool.

    The Human Risk Command Center is built for the organizations done waiting ’til Wednesday.
